Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Junkyard Gem: 1980 Chevrolet LUV Mikado

During the 1970s and into the 1980s, each member of the Detroit Big Three imported Japanese small pickups and sold them with Ford (Mazda Proceed), Dodge/Plymouth (Mitsubishi Forte), or Chevrolet (Isuzu Faster) badges here. Ford developed the Ranger and killed the Courier for 1983 (though Americans could still buy the Mazda-badged version all the way through 1993), while The General axed the LUV after the S-10 debuted in the 1982 model year. Isuzu sold the same truck as the P'up through 1987, though, and we might as well follow up our recent P'up Junkyard Gem with its LUV predecessor. LUV stood for Light Utility Vehicle, and I've managed to spot a handful in the boneyards over the years. This one now resides in a yard in northeastern Colorado. The Mikado trim package included striped seat upholstery and a sporty steering wheel, plus these cool dash badges. As far as I can tell, no LUV Mikado advertising featured any Gilbert and Sullivan tunes. This one is fairly rusty for Front Range Colorado, and it has endured a bed swap from some other small truck. The engine is the 75-horse Isuzu 1.8-liter. Members of this engine family went into everything from Chevy Chevettes to Isuzu Troopers in the United States. Very unusually for a small pickup during the Malaise Era, this one has a luxurious automatic transmission. Acceleration must have been a leisurely affair in this truck. Air conditioning? Unheard of! Someone stuck every one of their lunchtime apple stickers on the driver's door. After 41 years of work, this truck is done. Come on strong in a LUV of your own!
